To find a rational number between 2 and 214 using the method of adding the numbers together and dividing by 2, we add the two given numbers together:
2 + 214 = 216
Then, we divide the sum by 2:
216 / 2 = 108
Therefore, 108 is a rational number between 2 and 214. In mixed number format, it can be written as 108/1.

First, we need to convert the mixed number 2 1/4 to an improper fraction.
To do so, we multiply the whole number (2) by the denominator of the fraction (4) and add the numerator (1):
2 * 4 + 1 = 9
The improper fraction equivalent of 2 1/4 is therefore 9/4.
Next, we add the two given numbers:
2 + 9/4 = 8/4 + 9/4 = 17/4
Now, we divide the sum by 2:
17/4 ÷ 2 = 17/4 × 1/2
To divide fractions, we multiply by the reciprocal:
17/4 × 1/2 = (17 × 1)/(4 × 2) = 17/8
Therefore, 17/8 is a rational number between 2 and 2 1/4. In mixed number format, it can be written as 2 1/8.

To find a rational number with one decimal place between the numbers √17 and √18, we can use the average method.
First, we calculate the average of the two numbers:
(√17 + √18) / 2 ≈ 4.201946665
So, the average is approximately 4.201946665.
To get a rational number with one decimal place, we round the average to one decimal place:
4.201946665 ≈ 4.2
Therefore, a rational number with one decimal place between √17 and √18 is approximately 4.2.

To find a rational number between √10 and √11, we can take the average of the two square roots.
The average of √10 and √11 is (√10 + √11) / 2.
Approximating the square roots, we have (√10 + √11) / 2 ≈ (3.16227766017 + 3.31662479036) / 2 ≈ 3.239451225.
Therefore, an example of a rational number between √10 and √11 is 3.239451225.

An example of a rational number that is between √10 and √11 is 16/5.
To verify this, we can approximate the square roots:
√10 is approximately 3.16227766017
√11 is approximately 3.31662479036
And we can simplify 16/5:
16/5 is 3.2
Therefore, 3.2 is a rational number between √10 and √11.

3.2 isn't an answer choice
Apologies for the confusion. In that case, an example of a rational number that is between √10 and √11 would be 10/3, which is approximately 3.333.
the only answers that have decimal's are 3.1 & 3.4
Apologies for the oversight. In that case, an example of a rational number between √10 and √11 would be 3.4.
